In a codebase I work in, NHibernate needs an HttpContext to get its current session – like this:


public static ISession GetCurrentSession()
{
var context = HttpContext.Current;
var currentSession = context.Items[CurrentSessionKey] as ISession;
...


To get my hands on a session for a NUnit test – I put this in the setup:


HttpContext.Current = new HttpContext(
new HttpRequest(null, "http://tempuri.org", null),
new HttpResponse(null));


Also, I wipe the context in the teardown:

<code>

[TearDown]
public void TearDown()
{
HttpContext.Current = null;

}

</code>
